Quarantine Tanks

  • An extra tank so that you can isolate a sick fish to prevent the spread the of disease to the other fish. You can also put newly purchased fish here for a while to make sure they don’t have disease before introducing them into the main tank.
  • As soon as you see that a fish is acting strange (ie. not eating, sitting on the bottom, hiding away from the other fish) it’s a good idea to take it out of the main tank.
  • The quarantine tank should always be running and ready so that you don’t have to start the nitrogen cycle since this would be stressful for a sick fish.
  • If you don’t have space to keep a second tank then there are “tricks” to reduce the effects of the nitrogen cycle.
  • You should try to move as much beneficial bacteria as you can into the quarantine tank so that they can break down the fish waste.
  • Take gravel, plants, water, and rocks from the main tank and put it in the quarantine that you’re setting up.
  • Take some media from the main tank’s filter and put in the filter of the quarantine.
  • Change one third of the water as much as you can(3 times a week) so that fish waste doesn’t build up.
